Many studies show that Horse Chestnut Seed Extract treats poor leg circulation
Centella Asiatica improves the rate of wound healing
Centella Asiatica is an herb that grows in western Asia, South Africa, and Australia. If Centella Asiatica is fed to animals or applied to their wounds it improves the rate of healing and the formation of collagen in the wound.
Centella also may have an ability to improve swollen-damaged tissue. The Monograph of the herb is available in the March 2007 issue of Alternative Medicine Review.
Chronic venous insufficiency (CVI) is the term for when veins do not channel the flow of blood adequately and the most common site is in the legs. The three common causes are damaged valves in the veins allowing the blood to flow backwards, or a blood clot in the leg causing blockage, or narrowing of blood vessels due to plaque build up. They all result in ongoing swelling (edema), pooling of blood in the legs (venous stasis), and if left untreated they lead to discomfort and leg ulcers that heal poorly. The skin typically becomes thin and discolored, and the legs and feet often swell significantly. Horse Chestnut Seed Extract (HCSE) is commonly used to treat CVI alleviating the symptoms including reducing swelling of the leg, foot, and ankle. In this collation, four clinical trials in patients with CVI and one study of patients with varicose veins found that a HCSE tablet decreased swelling in the legs, and alleviated leg pain, heaviness and itching. The review is published in the January-February 2006 issue of the journal Advances in Therapy.
